  • Observed annually on July 29 to honor King Rama IX's royal contributions
  • Rooted in the creation of 'Lai Sue Thai' by King Ram Khamhaeng the Great in 1283
  • Officially established as a national day by the Cabinet resolution in 1999
  • Aims to promote accurate speaking, reading, and writing of the Thai language

Every year on July 29, Thailand observes a dedicated day to commemorate the evolution of the national language while campaigning for citizens to use Thai accurately in speech, reading, and writing, alongside efforts to preserve the linguistic heritage for future generations.

Looking back at historical roots, the inception of the Thai language is tied to the invention of "Lai Sue Thai," believed to have originated around 1283 when King Ram Khamhaeng the Great devised the Thai script. He adapted elements from Mon and Khmer scripts, establishing consonants, vowels, and tone marks to accurately convey Thai sounds and meanings before it gradually evolved into the modern script used today.

The invention of Lai Sue Thai during the Sukhothai period represents a crucial historical milestone, providing the kingdom with a distinct written system to record social and legal developments while establishing a unique cultural identity.

The formal designation of National Thai Language Day stems from a significant event on July 29, 1962, when His Majesty King Bhumibol Adulyadej (Rama IX) attended an academic panel discussion on "Problems of Thai Word Usage" hosted by the Thai Language Club at the Faculty of Arts, Chulalongkorn University.

"Thai people should preserve the correct usage of the Thai language, including pronunciation, word choice, and sentence structuring, and make good use of existing Thai words before coining unnecessary new terms."

During that royal appearance, His Majesty delivered an address reflecting his deep concern over Thai language usage, emphasizing that citizens should maintain correctness in pronunciation, terminology, and sentence composition, while fully utilizing existing native words before introducing unnecessary new vocabulary.
